How Often to Add Salt to Water Softener? – Explained by Experts

Salt is an essential element in a water-softening system. It is therefore quite essential and important to find when to add more salt to the system. It is also a good option to check how often to add salt to water softener. 

It is advisable to add a bag of salt every month to the water softener. Check the salt level at the beginning of the month and that should ideally provide you a better insight into how often and when to add salt to the water softener.

How Often to Add Salt to Water Softener?

There can be a number of reasons behind how often you need to add salt to the water softener. If your home has a high degree of water hardness, it is advisable to go with a frequent addition of salt to the water softener. If your water supply has a higher concentration of calcium and magnesium ions, it would require you to add more salts and add them more often as the softener will use more salt per gallon of water.

Yet another factor that would determine how often you need to add more salt can also be dependent on the water usage at your home. If you are using above average volume of water for day-to-day usage, you will need to use more water to be softened. The system will need to regenerate more and subsequently require you to add salt more often. 

Factors Affecting How Often Should You Add Salt to Water Softener

The only thing that you need to take care of is to take absolute care about the water softener and its proper maintenance. Adding salt to the brine tank periodically and checking out the proper functionality would make it a formidable choice to go with. 

A few factors that may affect the usage of salt and how often you need to add salt can include 

The hardness of water in your region 

The amount of hardness of the water in your area can be one of the deciding factors that would affect the amount of water and salt used. The water-softening resin is likely to exhaust really quickly and that would make the system regenerate very faster. That would make you add more salt to the water softener

Consumption of water 

The water consumption is yet another factor that would decide the amount of water to be softened. If your household consumes a lot of water, you are likely to run into a faster usage pattern for the salt and thus end up needing to add more salt quite often. 

Size of the water softener 

The size of the water softener will also be a major role in deciding the amount of salt consumed. If you have a larger water softener, you will find the brine tank to be larger enough. It would be large enough to hold more salt and thus does not require a frequent addition of salt to the tank. 

Age of the equipment

The age of the equipment used for the water softening can also have a bearing on how often you need to add salt to the softener. The volumetric softeners are known to consume less salt than the timed controlled softeners. The age of the device is yet another factor that you may need to pay special attention to.

How Do You Know If a Water Softener Is Running Out of Salt?

If you find the level of salt lower than that of the water, it should be a clear indication of the fact that the water softener is running out of salt. The lack of salt in the water will translate into the lack of soft water. You can detect the effects of hard water instantly when washing the dishes and laundry. 

You will also notice that the water has a formation of scum and stained surfaces. Limescales appearing on the faucets and other plumbing equipment can also be a good indicator of the fact that the salt is running out in the water softener. The shower heads may also develop a crusty coating. 

How to Check How Much Salt Water Softener Has?

The best and simplest option is to lift the cover of the brine tank and check if the salt level is good enough and sufficient. If you find the salt looking dry and the salt is filled to the half level, it can be an indication that the salt is needed to be replenished. 

If you find the brine tank is half full and the salt appears to be dry, it would indicate that the salt concentration is low in the brine tank. You can also check the sides of the chamber walls and check if it has any sticky ions. The sticky ions will indicate a lower amount of salt in the water. 

How Long Does Water Softener Salt Last?

The salt should ideally last two to three months. The salt can either be quite coarse or in the pellet form. The right option is to top up the salt with the 40 pound bag per month. The salt inside the water softener should ideally last a couple of months. 

Most manufacturers recommend adding at least 40 pounds of salt to the water softener every month. The exact amount of salt would largely be dependent on a wide range of factors that would include your water and salt usage, your softener’s regeneration programming, and the size of the brine tank. 

There are a few specific factors that would determine how long does water softener salt last –

The hardness level of your water supply

The hardness of your local water supply would assume a lot of essence and importance in determining how long can water softener salt can last. If you have very hard water it would contain a lot of calcium and magnesium ions and that would require more salt than moderately hard water would need. The resin will get depleted at a very faster rate. 

Your water quality 

The quality of the water can be yet another prime factor that would decide the salt consumption in a water softener and how long does the water softener salt last. If your water supply contains a huge amount of iron, you are likely to run into a high consumption of salt. If you have a very high percentage of iron in your water supply, we would suggest using an iron removal water filter along with the water softener. 

Quality of the salt 

The quality of the salt should be yet another factor that may need attention. High-quality and high-purity salt will last longer. It is highly recommended to make use of the evaporated salt as it is found to be more practical in providing a powerful efficiency. Low-quality salt can clog the brine tank as it contains impurities. 

Size of the brine tank

The size of the tank will also determine the amount off salt used by the water softener. The more salt that the brine tank can hold, less frequently you need to add the salt. The size of the tank, however, does not have a say in how long does water softener last. 

The Closing Thoughts

How often to add salt to water softener can be dependent on several factors. The discussion here should ideally be helpful in letting you arrive at the best options to find how often you should add salt to the water softener. 

Some FAQs That May Be Interesting

How do I know when to add more salt to my water softener?

You can lift the cover of the brine tank and check the salt level available. If the salt is below the level of water and is filled just to the half filled mark, it would need a refill urgently. You will also need to fill the salt up if you notice that the salt is too dry.

How long does the salt last in a water softener?

The salt in the water softener should last at least 3 to 4 months. The exact durability of the salt would also be dependent on multiple factors such as water hardness, quality of the water and the amount of water consumption. The salt that is still unused generally does not have an expiry date.

What happens if salt is too low in water softener?

The lack of salt or a lower level of salt in the water softener will translate into water being not softened. The entire plumbing system will be filled with the hard water. This can damage your heater and other valuable equipment.
